Use the attached math problem and my working. If a symbol, line or diagram is unclear, quote the ambiguous part and ask me to clarify; do not silently guess. First transcribe the problem and number my steps. Check each step against the previous one, preserving units, domains and conditions. Identify the first incorrect or unsupported step rather than only giving a final answer. Explain the specific rule involved and give one small hint, then wait for me to try again. If all steps are valid, explain how to verify the result independently. After I request the full correction, show a concise worked solution and substitute the result back into the original problem. Distinguish an arithmetic slip from a conceptual misunderstanding. Do not infer a learning ability or diagnosis from one attempt.
Find the First Wrong Step in a Math Solution
Use a photo or transcription of your working to locate the first unsupported step. Get a small hint before the corrected solution so you can keep learning.
